will.i.am should stick to the voice. at least there he'd be doing it for the talent rather than the theatrics of the x factor (of which he's been openly critical on more than one occasion). he'd lose my respect if he moved to XF cos imo it'd be for the money and purely the money.
I don't see why the 10th season should be the last season, sure ratings aren't as high as last year, but it's still ITV biggest show, why would they want to lose that?
Simon and Cheryl are the only two on that list who'd be choices for a "Big Bang" exit. The other two... Louis would obviously be there, and they'd try to get Dannii back for the 4th judge, and if they couldn't they'd probably try to get Sharon.
I highly doubt next year is the final year anyway.
I'm loving Nicole this season by the way, she has hit her stride and is doing a great job. Her first season on the US version was alittle wonky, and she was new at it so it was understandable, but now she is just a delight to watch and funny.
